If you click on the Interpret Data as Image node's Data input port, the popover shows that it has a data type of Binary Data. In Vuo, Binary Data represents raw bytes, the way information is stored in a file or in memory. That's the abstract definition. For the practical definition, all you really need to know is that you can connect this port to any output port of type Binary Data.

If you search the node library for "binary data", the first result is the Fetch Data node, so let's start with that. With Fetch Data -> Interpret Data as Image, you can make a glitchy image from the bytes of any file. InterpretData-file.vuo

Another node that comes up in the search is Make Data from Bytes. This is a nice one because it lets you convert numbers to bytes — so, anything you can convert to numbers, you can then convert to an image. For example, audio samples. InterpretData-audio.vuo

Or you can make a patterned image using math, like Make Points along Line or Calculate List. InterpretData-math.vuo

If you broaden the node library search to "data", you'll see some additional nodes that output Binary Data, such as Receive Serial Data and Convert Text to Data. You could also connect those to Interpret Data as Image.

Maybe others in the community can give examples of how they're using Interpret Data as Image.

Closing this bug report since there's no action we can take at this time. But if anyone can provide enough information to reproduce the problem, we can reopen it.
